Save a copy of the current state's registers
This API should be used to efficiently make or update a saved copy of the
state's registers.
@uc: handle returned by uc_open()
@buffer: pointer to the region to store the registers in. The first call to
this function should pass NULL in this parameter, so a region of the
appropriate size for the current architecure can be allocated. Further calls
to this function may pass in the return value of previous calls.
@return a pointer to the region the registers were saved in. If buffer was
NULL, this is a newly allocated region, otherwise it is the same as buffer.
Any allocation performed by this function must be freed by the user.
